Incorporation of diethylamine and hexylamine allowed determination of the degree of polymerization (DP) of the obtained polymers by 1 H NMR. The DP depended linearly on the M/I ratio, for both diethylamine and hexylamine, with higher DPs for the diethylamine-initiated poly- L -lysine at equal ...
In-house made immunoaffinity columns were equilibrated with phostphate-buffered saline (PBS) pH 7.4, and elution was done with 100 mM Tris, 400 mM NaCl, 5 mM EDTA, 20 mM diethylamine, pH 11.5. Proteins were concentrated using Amicon 30 kDa MWCO centrifugal filter units as per ...

Particularly useful tertiary amido amines herein include: stearamidopropyldimethylamine, stearamidopropyldiethylamine, stearamidoethyldiethylamine, stearamidoethyldimethylamine, palmitamidopropyidimethylamine, palmitamidopropyldiethylamine, palmitamidoethyidiethylamine, palmitamidoethyldimethylamine, behenamidopropyldimet...
Briefly, soluble proteins were extracted using cold 0.4% diethylamine in 100 mM NaCl, spun at 135,000 × g for 1 h at 4°C, and neutralized by adding 0.5 M Tris-HCl, pH 6.8. The pellet was further extracted using 70% cold for- mic acid, sonicated for 1 min, spun as above, and...

Formation of nitrosamines in alkaline conditions: a kinetic study of the nitrosation of linear and cyclic secondary amines by nitroalkanes A study has been made of the nitrosation of sixteen secondary amines, six alkylamines (dimethylamine, diethylamine, dipropylamine, diisopropylamine, dibutylamine, diis...
Step II: product 1 or 2 (1 equiv.) and electron-donating part (diethylamine,N-methylaniline or indoline) (1 equiv.) were dissolved in DCM. The mixed solution was stirred under 30 °C for 2 h. After removing the solvent by a rotavapor, the rough product was purified by chromatograph...
